Thanks again , I,d thought about moving it all into 1 bay so I,m definitely going to try it tomorrow ,then if it works I,ll get more , it's about £70 for 100 ltr here so not expensive, I,v just done a refurb on the pond retro fitting 2 extra bottom drains and another set of filter chambers giving me...

Still having problems , I,v changed the air discs to 10 large ordinary air stones 5 in each chamber the chambers are 1 m square but same problem now 5 holes and discs not moving around I even tried halving the air supply but it did,not help . I wondered if not enough media ? 50 litres in each bay gi...
